Validate Smart Breath Analyzer as Screening Tool for Diabetic, Hepatic, Renal, Lung, and Other Metabolic Disorders (RESPYR-SBA)

9. juni 2026 opdateret af: Respyr

Early Identification of Metabolic Function Derangements Such as Diabetes, Liver, Renal Issues by Respyr Smart Breath Analyzer and Its Validation as a Screening Tool Among Diseased and Healthy Controls

This is a prospective, multicentric, non-treatment study to build and validate a portable, non-invasive smart breath analyzer that can screen underlying health issues using exhaled breath. The study will be conducted with healthy participants and participants with known cases of diabetes, kidney related issues, liver related issues, and lung related issues as confirmed by pathology reports. In phase 1, 500 apparently healthy individuals with normal levels of fasting and postprandial blood sugar, renal function test, liver function test, and lung function test will be recruited. In phase 2, 500 patients of type 2 diabetes, liver function, renal function, and lung function derangements each diagnosed by 10% increment above normal values will be enrolled. In phase 3, validation of the breath analyzer as a screening tool for early identification of type 2 diabetes, liver, renal, lung and other metabolic function derangements will be done by randomly assigning healthy and diseased participants for exhaled breath sample analysis. The study is based on the principle of exhaled breath analysis where parts per million and parts per billion level of volatile organic compounds and gases in human breath will be measured. AI based algorithms will be generated to effectively screen unhealthy biomarker levels, enabling timely preventive action.

Detaljeret beskrivelse

The smart breath analyzer, Respyr is an IoT and deep-tech enabled portable device developed by Humors Tech Pvt Ltd, Bangalore, India. The device measures volatile organic compounds (VOCs) and gases at parts-per-million and parts-per-billion levels in exhaled breath using AI and ML-based algorithms to identify metabolic derangements non-invasively.

Registration Details:

The study is registered with CTRI (CTRI/2022/09/045983) and ethics approval has been obtained from the Institutional Ethics Committee of JSS Medical College, Mysore (Ref: JSSMC/IEC/260822/07/CT Final Approval/2022-23, dated 19.12.2022). Protocol number: HTB-PROTOCOL-01, Version 1, dated 07 March 2022.

Testing Procedure:

Participants will provide an exhaled breath sample under fasting conditions, or with a minimum gap of 1 hour after consuming water and 3-4 hours after consuming food. The breath analyzer readings will be compared against standard laboratory diagnostic values including FBS/RBS, RFT, LFT, spirometry, and lipid profile, all tested within 15 days of participation.

Regulatory Compliance:

The study follows ICH-GCP guidelines, CDSCO-DCGI and New Drugs and Clinical Trial Rules 2019, and ICMR Ethical Guidelines for Biomedical Research on Human Participants.
